Guns are not like the other items mentioned, as with guns, the more one gets, the more one wants.
If I get a toaster, I don’t want one hundred of them.
That’s far from universal. While some people want many guns, most people are content with one or a few. Some people also collect cars, having many, certainly more than others might think they “need”.
So what the gun industry wants to know is when will the majority of gun owners be satisfied enough to no longer want to buy another gun? An incredibly hard question to answer.
They can, however, clap their hands with glee whenever some ignorant socialist Democrat calls for more gun control, because they know their sales are about to jump.
I see guns like tools. Different tools for different jobs. A .308 for big game/zombies, a 12/20 gauge shotgun for fowl/home defense and a .22 rifle for small game. A handgun for CCW.
